This invention relates to aryl aliphatic ethers which contain an aromatic nucleus substituted by an aminomethyl group and to a process for preparing such ethers. More. particularly this invention relates to ethers of the formula (ZCHz) nArXAY wherein Z is a secondary amine group, a tertiary amine group, or a quaternary ammonium group, n is an integer having a value of one or two, Ar is a carbocyclic aromatic nucleus, X is oxygen or sulfur, A is an alkylene group, the chain of which may be interrupted by oxygen or sulfur, and Y is a polar group based upon the elements carbon, hydrogen, halogens, oxygen, and nitrogen, including such groups as OH, O-a1kyl, -O-ary1, CO-alkyl, -CO-aryl, --OCO-alkyl, -OCO- aryl, -COOH, --COO alkyl, -.-CONHR',

-CONHR.", --ha1ogen, -NR'R", or

-NR.'R"R' anion, R'-R" representing hydrogen or aliphatic, cycloaliphatic, arylaliphatic, heterocyclic, or aryl groups.

The aminomethyl ethers of this invention may be prepared by reactingan amine with an aryl aliphatic ether having a nuclear halomethyl substituent of the formula (halogen CI-IzMArXAY in the presence of a strong base, such as sodium hydroxide, potassium hydroxide, benzyl trimethyl ammonium hydroxide, barium hydroxidacalcium hydroxide, etc. 7

' (ClCHz) nC6H4n(CHa) OCH2CH2OCsH4-a nitro, halogen, acyl, or other group which is stable under the conditions used in the preparation of the halomethyl ethers, that isfin the presence. of a hydrogen halide and formaldehyde.

Thi requirement excludes phenolic hydroxyl, amino, diazo, and aldehyde groups. The aromatic nucleus may be mononuclear orv polynuclear, as in benzene, naphthalene, phenanthrene, anthracene, diphenyl, etc.

As reactant with one of the above halomethyl aryl aliphatic ethers there is used a primary, secondary, or tertiary amine to yield secondary or tertiary amines, or a quaternary ammonium salt. A product in the form of a tertiary amine may be converted by reaction with an alkylating 0r aralkylating agent into a quaternary ammonium salt. The reacting amines may be members of the aliphatic, arylaliphatic, cycloaliphatic, or-

'aryl series or may contain substituents from two or more of these series. Typical amines include anethylamine, ethylamine, isopropylamine, butylamine, amylamine, octylamine, isooctylamine, caprylamine, decylamine, dodecylamine, octadecenylamine, octadecylamine, allylamine, methallylamine, hydroxyethylamine, hydroxypropylamine, benzylamine, methylbenzylamine, aniline, chloroaniline, cyclohexylamine, methylcyclohexylamine, dimethylamine, diethylamine, dibutylamine, diethanolamine, diallylamine, dimethallylamine, diisooctylamine, dodecylmethylamine, octadccylmethylamine, methyl benzylamine, dicyclohexylamine, methylaminobenzene, cyclic amines such as morpholine, piperidine, pyrrolidine, etc. In fact, any primary or secondary monoamine appears to be useful in forming the prepared.

aminomethyl aryl aliphatic ethersof this inven: tion. Primary and secondary aminesare characterized by the presence of ahydrogen atom attached to the amino nitrogen atom thereof. It will be'noted-that, in the cases of such amines as morpholine and pyridine, the groups attached to the nitrogen are dior tri-valent groups which form heterocycles with the-nitrogen.

The reaction between halomethyl .arylaliphatic ether and amine is carried out by reacting said ether'with an amine in the presence of a base at a temperature between about 20 C. and about 250 C. If desired, the reaction may be performed in the presence of a solvent, such as "dioxane, toluene, water, or the like. When several types of labile halogens are present in the ether, the reaction may be so conducted as to replace only one type or so asto replace all of the halogens. If the reaction is carried out above about 100 C., the various labile halogens are replaced by amine groups. Between -20 C.,and about 100 C., however, only the halogen o1 the halomethyl groups reacts. In a similar way the reaction product may be varied in the case of the ethers having -C OOH,.or '-COOR, or'-.'OCOR groups by variations in temperatures of reaction. Thus, in the lower range amines react only with the halogen of the halomethyl group, whereas in the upper temperature range there occursflnotonly the reaction withthe haiomethylgroup but also reaction with the carboxyl] group leading to monoor di-substituted 'carboxylic amides and to alcohols,

Because '0': thediflerence in reactivity of the different types of labile halogens, they may be replaced with one type of amino nitrogen group or with different such groups. Thus, the compound R'R"NCH2AIXC2H4C1 may be formed be- ;low 100 0. and this reacted above 100" c. to form ium salt by reaction with such compounds as the ,diallwl sulfates, as, for example, diethyl sulfate, alky1 halides as, for example, methyl iodide,

bromide,-or chloride, benzyl halides, esters, as for example, methyl formate,ethyl' chloro-acetate, or methyl-p-toluene sulfonate, alkyl halomethyl ethers as, for example, bromomethoxybu tane, or a halomethyl aryl ether, such as chloromethyl phenoxyethyl chloride, etc. a b When a salt of anamine is desired, it may be formed by the addition of an acid to an amine. Salts of both inorganic and organic acids may be The amino ethers of this invention may be used as textile finishing agents, disinfectants, bactericides, wetting agents, detergents, insecticidal preparations, drugs, fungicides, etc.
